I'm buying parts now that broke that. Shouldn't have. Long story. It will be reliable, but not maintenance free.
The problem with the 570 is AHC, I haven't researched it enough to see if it can be deleted like my 470. The bumpers can fit, just takes a bit more work.
If you are only lightly modding, then the LX is by far the way to go, as the used cost is cheaper AND it's more luxurious.
They are the same car, one just has a better interior at the cost of the nasty Vader grill.
